My engine dies when I turn on my fan on high and the battery is drained.
Is it it the blower fan motor draining energy out of the battery or the alternator has a problem. Everything else, like the wipers, headlights and radio works fine but as soon as turn on my fan, the engine loses power and the battery is dead. I boosted the truck and it starts right away and everything works but as soon as I turn on the fan…the engine loses power and dies.

Shorted fan or wiring.
